Last night, at a meeting of the Mission Bay Citizens Advisory Committee, Warriors execs outlined the project. The Examiner has a great writeup, but here are some of the most important details: The 18,000 seat arena will be 135 feet at its tallest point, and flanked by two 160-foot tall office towers, which will include 55,000 to 95,000 square feet of ground-level retail space.There will also be a plaza with Bay views. Below the site will be a 700-car garage.
